Research Interest

  • Computational Integral Imaging is a powerful technique which derived from 4D Light-field imaging. It allows us to record and display 3D scenes with greater quality as compared to the conventional 3D imaging methods. It’s an autostereoscopic approach i.e., 3D images/videos it produces do not require a specialized equipment (3D-glasses).
  • Photon Counting Imaging is a method which can detect individual photons in completely dark environments. This allows us to perform real-time imaging in ultra-low-light-level scenarios.
  • Difficulties associated with data transmission has become ubiquitous as demand for internet facilities such as high-quality video streaming is ever increasing. One such concern is the protection of this vast data against theft and eavesdropping. Optical Encryption has facilitated a scalable prevention against these threats.
